Heya!!! User!!! ✌

Here's your answer friend,

==============================

==> (2√7 + 3√5)(2√7 - 3√5)

==> Therefore, by using the { (a + b)(a - b) = a² - b² } identity

we have,

==> {(2√7 + 3√5)(2√7 - 3√5)}

==> {(2√7)² - (3√5)²}

==> {28 - 45}

==> -17

================================
Is the required answer.

HOPE IT HELPS YOU :)
